Ultrasonic Distance Sensor Module – HC-SR04

Features :

1. Ultra-Low Power: 40µA in measurement mode, 0.1µA in standby@ 2.5V.
2. Free-Fall Detection.
3. Tap/Double Tap Detection.
4. Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command
5. Wide temperature range (−40°C to +85°C).
6. 10,000 g shock survival.
7. Support 5V/3.3V voltage input, onboard RT9161 power chip, lower pressure drop faster than 1117, the faster load speed of response, very suitable for high-noise power supply environment.
8. User-selectable resolution
   1. Fixed 10-bit resolution.
   2. Full resolution, where resolution increases with G range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all G ranges).
